Updates an order, to reflect the fact that it was received, at least

If a partial order is received, splits the order into two.

Updates the order with biblionumber C<$biblionumber> and ordernumber

    ordering     => 1 # boolean representing order stage
});


Sets calculated values for an order - all values are stored with full precision
regardless of rounding preference except for tax value which is calculated
on rounded values if requested

For ordering the values set are:
    rrp_tax_included
    rrp_tax_excluded
    ecost_tax_included
    ecost_tax_excluded
    tax_value_on_ordering
For receiving the value set are:
    unitprice_tax_included
    unitprice_tax_excluded
    tax_value_on_receiving

Note: When receiving, if the rounded value of the unitprice matches the rounded
value of the ecost then then ecost (full precision) is used.

Returns a hashref of the order
